Key findings

  • The brain predicts both the content and the timing of sensory events
  • Neural oscillations are proposed as the mechanism for these predictions
  • Different rhythms suit predicting 'what' and 'when'

DOI 10.1016/j.tics.2012.05.003 → PubMed 22682813 →

A review of how the brain's rhythms help it anticipate what will happen next. The authors separate predicting what a sensory event will be (predictive coding) from predicting when it will happen (predictive timing), and argue that different oscillation frequencies offer different solutions to each. It gives a functional account of why particular EEG rhythms matter for perception.
